SPECIFICATION forming part of Letters Patent No. 334,965, dated January 26, 185 6.

To all whom. it may concern.-

Be it known that I, SAMUEL B. MoConKLE, of Chattanooga, Hamilton county, Tennessee, have invented a new and useful Improvement in Swings, of which the following is a specification.

My invention relates to improvements in those automatic swings which are capable of being set in motion by the occupant.

My improvements consist in certain details of construction hereinafter described, and pointed out in the claims.

My invention is an improvement on those swings which are provided with front and rear suspenders; also on those swings having aplay-board threaded on the front suspenders; also on those swings having a foot-board adjustable vertically and horizontally and supported partly on the seat and partly on sus- 2c ponders independent of the seat, and also on those swings adapted to be suspended on extensionthougs.

In the accompanying drawings, Figure l is a perspective View, and Fig. 2 is a side elevar 2 tion, of a swing embodying my invention. In Fig. 2 the seat is shown partly in section.

A represents a seat,which is suspended by cords B G from any horizontal fixture, D, B being the front cords, and G the rear cords.

0 For this purpose each cord,being bent double, as at I), receives in its loop or bight thus formed a hook, E, which engages in an eye, F, secured in the said fixture. Thelower extremities of the said cords, being passed through 5 holes near the corners of the seat, are knotted underneath the same, as shown at 0. Before such attachment to the seat, said cords are rove through orifices in the back G, arms H,

and tubes 1, as shown.

When desired for use by infants or young children, the front cords are also rove through orifices in the rear side of a table or play-board, J, through orifices on the other or front side of which is rove another cord, K, whose looped 4 5 extremities 7c engage in the same eyes or hooks,

E, from which depend the cord B (1. Two

pairs of cleats, L, form two dovetail grooves, L, on the under side of the seat A, which receive and hold the correspondingly-ibrmed 5g sliding blocks M of legs N, having several pairs or couples ofloops or rings, O,for the reception of hooks P at the rear edge of the foot-board Q, whose front edge is supported in the bight of a cord, R, which, being engaged around one or other hook S on the under side of the said fbot-board, occupies notches q in said board. Loops r at the extremities of cord R receive hooks T, which engage in eyes U, that may be secured in the same fixture that receives the eyes F, but somewhat 6 farther back and wider asunder than said eyes l The cord It has two, knots, r, near its middle, whose engagement on opposite sides of hook S prevents lengthwise displacement or shifting of said cord relatively to the foot-board. Spring-catches V on the under side of the seat A, by engaging behind one or the other pairs of keepers \V, that project from the under side of the said blocks M, serve to prevent accidental separation of the legs N and their attached foot-board from the seat. For use by a small child, the said blocks are pushed in until the spring-catches engage behind the forward keepers; but for larger occu pants they are only pushed in so far as to bring the rear keepers into engagement behind the said spring-catches.

The swing may be adapted for suspension from greater heights by a provision of extension-thongs X.

The swing is set in motion by the occupant leaning forward and pressing with his feet upon the front edge of the foot-board, so as to disturb the center of gravity and cause the chair to sway rearward. As the chair nears 8 5 its rearmost position, the occupant, by assuming the erect or even a back reclining posture, reverses the position of the center of gravity and aids the recoil in producing a forward sweep of the chair, when the first motion may 0 be repeated, and so forth.

Entrance to or exit from the chair is facilitated simply by shifting the play-board J to a greater height upon the cords, to which position the sag of its front portion operates to re- 5 tain it, as shown in Fig. 1. For use by larger persons, such elevated position of the playboard may be retained during occupancy of the swing; or the play-board and the rope K may be removed altogether.

by which the front edge of the platform or i table is supported, substantially as set forth.

2. In a swing, the combination of a seat, front suspenders, B, rear suspenders, 0, legs N, secured to the bottom of the seat, and having series of paired rings 0, foot-hoard Q, having hooks P secured to its rear edge and engaging the rings 0, and a suspender, R, supporting the front edge of the board, substantially as set forth.

3. In a swing, the combination of a detachable foot-board whose legs N have dovetailed blocks M, that engage in corresponding grooves, L, on the seat A, and are retained by springcatches V and a series of keepers, W, i substantially as set fort-h. 4. In a swing, the combination of a seat, A,

paired cleats L, forming grooves L, blocks M, sliding in the grooves, legs N, secured to 5' the blocks, and a foot-board supported on the i legs, substantially as set forth. i 5. In a swing, the combination of a seat, A, having grooves L, blocks M, sliding in the grooves, legs N, secured to the blocks, afootboard secured to the legs, and the spring catchesV and series of keepers XV, substantially as set forth.

6. In a swing, the combination, with the knotted cord R, of the series of kooks S on the under side of the hinged foot-board Q, as and for the purpose set forth.

In testimony of which invention I hereunto set my hand.
